Building an AI chatbot that actually retrieves answers from your own documents usually means stitching together a language model, a database, and some retrieval logic — normally a real coding project. Flowise turns that into something closer to connecting boxes on a whiteboard: drag a model here, a document loader there, draw a line between them, and you have a working AI pipeline. Flowise is an open-source, drag-and-drop visual builder for constructing LLM-powered applications, AI agents, and retrieval-augmented generation (RAG) pipelines without writing code. It offers two workflow types: Chatflow, for linear, sequential pipelines good for Q&A bots and simple retrieval, and Agentflow, for autonomous agent loops where the model decides which tools to call, suited to research and multi-step tasks. It integrates with over 100 tools including LangChain and LlamaIndex, and — notably — it's free and self-hostable since the underlying project is fully open-source. In August 2025, Workday acquired Flowise, folding the visual agent-building technology into its enterprise HR and finance products, while the open-source project continues independently.
